SPECIFICATION forming part of Letters Patent No. 369.254, dated August30, 1887.

Application tiled October 18, 1886. Serial No. 216.483. (No model.

To aZZ whom, it may concern.-

Be it known that I, EDWIN LoUnEEnAoK, a citizen of the United States,residing at the city and county of Philadelphia, and State ofPennsylvania, have invented certain new and useful Improvements inWindow-Blinds, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, of which-Figure l is a front elevation of the upper part of a mountedwindow-blind provided ,with my improvement. Fig. 2 is a side elevationof one of the end brackets to which the top slat of the blind ispivoted. Fig. 3 is a transverse vertical. section as on line xx, Fig. 2.Fig. 4 is a slightly-modified form of the bracket.

This invention relates to an improvement inthe inode of mountingVenetian 7 windowblinds; and it consists in the combination, with one ofthe end brackets to which the top slat of the blind is pivoted, of apulley or sheave journaled therein, over which pulley and like pulleysin said pivoted slat run the cord or cords for raising or lowering theblind, as hereinafter more clearly set forth and claimed.4

Referring to the annexed drawings, Amarks the windowfranie; B, theblind; C C', the end brackets` from which the latter is suspendedr D,the upper slat, which is pivoted t0 said brackets, and E the cord orcords for raising or lowering the blind.

As seen in Figs. 2 and 3, the upper part of bracket G has formed thereona pair of lateral lugs, Z, between and in which is journaled a smalldouble-grooved pulley or sheave, s, over which the cords E run, anopening, o, through which said cords pass, being formed in the bracketat the rear of said pulley. Que end of this bracket C is provided withthe usual perforated plate or flange, f,whereby the bracket may bescrewed to the side of the window-frame, and also a hole, :0, for thereception of thepivot-pin of the Slat. The op posite bracket, C, is ofusual construction, the other end of the upper slat being pivotedthereto. This Slat D has formed therein at the points where the raisingand lowering cords pass longitudinal slots z, in which are journaledgrooved pulleys 1J. The two cords E, which are secured to the bottomslat, (not showm) pass up through openings in the various slats in theusual manner, and over the pulleys p p, respectively, in the upper Slat,and the pulleys Vin the bracket C', extending down within convenientreach.

The blind is operated in the usual mannert'. e., if it be desired toraise the blind, the cord or cords E are pulled downward, therebydrawing up the lower slats, and if desired to lower the blind the cordsare released, the slats being opened and closed or adjusted to variousangles by means oi the cord G on the opposite side, which is secured tothe slat D.

Vith the construction above described it is Obvious that I am enabled todispense with the upper box or casing (secured to the window-frame) fromwhich the blind was suspended heretofore, which box or casing containedthe pulleys over which run the cords E. I therefore not only cheapen andsimplify the construction of the blind, but also improve the appearancethereof.

rIhe modification shown in Fig. 4L consists merely in forming theliangef at the upper end of the bracket, in order that the latter may besecured to the top piece of the window-frame when it would be otherwiseinconvenient to secure the same to the side of the frame, owing tobeading, Ste.

Having thus described my invention, I claim as new and wish to secure byLetters Patent#- 1. The pulley-bracket for blinds of the class recited,provided with the grooved sheave journaled between the lugs Z, adownward extension provided with the pivot-hole af, and the liange f,all constructed and combined substantially as and for the purposespecified.

2. The combination, with the blind having its upper slat provided withthe pulleys p p and cords E and G, of the bracket having the lugs Z, andthe sheave journaled between the same, the downward extension of saidbracket having the pivothole x, and the end of the upper slat pivoted insaid hole, all constructed, combined,and adapted to operatesubstantially as and for the purpose recited.

In testimony whereof I have hereunto affixed my signature this 14th dayof Cctober, A. D. 1886.
